Nash's bargaining problem and the scale-invariant Hirsch citation index
Josep Freixas, Roger Hoerl, William S. Zwicker
A number of citation indices have been proposed for measuring and ranking the research publication records of scholars. Some of the best known indices, such as those proposed by Hi…
Bounds for the Nakamura number
Josep Freixas, Sascha Kurz
The Nakamura number is an appropriate invariant of a simple game to study the existence of social equilibria and the possibility of cycles. For symmetric quota games its number can…
Characterization of threshold functions: state of the art, some new contributions and open problems
Josep Freixas, Marc Freixas, Sascha Kurz
This paper has a twofold scope. The first one is to clarify and put in evidence the isomorphic character of two theories developed in quite different fields: on one side, threshold…
The cost of getting local monotonicity
Josep Freixas, Sascha Kurz
Manfred Holler introduced the Public Good index as a proposal to divide a public good among players. In its unnormalized version, i.e., the raw measure, it counts the number of tim…
The golden number and Fibonacci sequences in the design of voting structures
Josep Freixas, Sascha Kurz
Some distinguished types of voters, as vetoers, passers or nulls, as well as some others, play a significant role in voting systems because they are either the most powerful or the…
Enumeration of weighted games with minimum and an analysis of voting power for bipartite complete games with minimum
Josep Freixas, Sascha Kurz
This paper is a twofold contribution. First, it contributes to the problem of enumerating some classes of simple games and in particular provides the number of weighted games with…
On minimum integer representations of weighted games
Josep Freixas, Sascha Kurz
We study minimum integer representations of weighted games, i.e., representations where the weights are integers and every other integer representation is at least as large in each…
A Fibonacci sequence for linear structures with two types of components
Josep Freixas, Xavier Molinero, Salvador Roura
We investigate binary voting systems with two types of voters and a hierarchy among the members in each type, so that members in one class have more influence or importance than me…
The Complexity of Testing Properties of Simple Games
Josep Freixas, Xavier Molinero, Martin Olsen +1
Simple games cover voting systems in which a single alternative, such as a bill or an amendment, is pitted against the status quo. A simple game or a yes-no voting system is a set…
